<u>Answer:</u> The cell potential of the cell is +0.118 V
<u>Explanation:</u>
The half reactions for the cell is:
<u>Oxidation half reaction (anode):</u>
<u>Reduction half reaction (cathode):</u>
In this case, the cathode and anode both are same. So, will be equal to zero.
To calculate cell potential of the cell, we use the equation given by Nernst, which is:
where,
n = number of electrons in oxidation-reduction reaction = 2
= ?
=
= 1.0 M
Putting values in above equation, we get:
Hence, the cell potential of the cell is +0.118 V
Answer : 37 drops are delivered per milliliter of the solution.
Explanation :
The problem gives us lot of extra information.
We want to find the number of drops delivered in 1 milliliter here.
We have been given that, one drop of the solution delivers 0.027 mL of solution.
Let us use this as a conversion factor,
Let us find number of drops in 1 mL using this conversion factor.
Therefore we can say that 37 drops are delivered per milliliter of the solution.
